What is area of rectangle?

 A flat surface of a specific shape can be thought of as the area it occupies in space. It is calculated as a "number of" square units (square centimeters, square inches, square feet, etc.) The quantity of unit squares that can fit inside a rectangle is known as the area of a rectangle. The flat surfaces of laptop monitors, chalkboards, canvases, and other objects are a few instances of rectangular shapes. To determine the area that these items occupy, use the formula for a rectangle's area.

Here area of rectangle = 2[tex]m^2[/tex]

And width of the rectangle w= 4/5 m .

Using area of rectangle formula ,

=> A = h*w

=> 2= h*4/5

=> h = 10/4 = 2.5 m.

Therefore the rectangular design would be 2.5 m tall.

Answer:

apples 19%, bananas 38%, oranges 36%, and other fruits 7%

By taking the difference between the final distance and the initial distance we will see that the change in the distance is -23/24 feet.

First, we should define the system we will use.

Notice that "distance" is defined positive, then when you are behind your friend and when you are ahead, the distances are in both cases positive.

First, you are at (4 + 5/8) feet from your friend, and then you are at (3 + 2/3) feet from your friend.

The difference is given by the final distance minus the initial distance, so we have:

d = (3 + 2/3) ft -  (4 + 5/8) ft

We can decompose the mixed numbers into wholes and fractions, so we get:

d = (3 + 2/3)ft - (4 + 5/8) ft

d = (3 - 4)ft + (2/3 - 5/8)ft

d = (-1)ft + (16/24 - 15/24)ft

d = -1 ft + 1/24ft = -23/24ft

So the change in the distance between the end and the beginning is:

d = -23/24ft

As per the concept of distance-speed-time formula, the speed of Rachel is 38 meters per second

Distance-speed-time formula

The general time formula to calculate the distance-speed-time for any task is given as

[Time = Distance ÷ Speed].

And the SI unit of time is seconds (s).

Given,

Rachel is a stunt driver, and she's escaping from a building that is about to explode! And the variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt.

The function of d=-38t+220

Now, we have to find the speed of Rachel.

We already know that the speed is calculated as,

=> v = dx/dt

Here we have the distance is a function of time,

Now, we have to apply it one the given formula then we get,

=> v = d/dt( 38t + 220)

After the differentiation we get the value of

=> v = 38 m/s

Here the derivative of a constant (here 220) is zero.

Answer:

d = V- x

Step-by-step explanation:

To make 'd' as the subject, isolate 'd'.

To isolate d, subtract 'x' from both sides,

              d +x = V

        d + x - x = V - x

                  d = V - x

The formula using d as the subject is d = V-x.

The formula is d+x = V

The subject of the formula is nothing but a variable that is being worked out. Here, we have to convert the given formula to describe d as the subject.

According to the property of equality, the two sides of the equation should be balanced. To solve the given expression, we use the subtraction property of equality.

The subtraction property of equality refers to balancing an equation by using the subtraction operation on both sides of the equation.

Therefore, subtract x on both sides of the given formula,

[tex]\begin{aligned}d+x&=V\\d+x-x&=V-x\\d&=V-x\end{aligned}[/tex]

The gallons of first brand is 102 gallons and that of the second brand is 68 gallons.

According to the question,

We have the following information:

The first brand is 70% pure antifreeze, and the second brand is 95% pure antifreeze. 170 gallons of a mixture contains 80% pure antifreeze.

Now, let's take the amount of first brand to be x gallons and that of the second brand to be y gallons.

So, we have the following expressions:

x+y = 170

x = 170-y ....(1)

70x/100 + 95y/100 = (80*170)/100

70x+95y = 13600

Now, putting the value of x from equation 1:

70(170-y)+95y = 13600

11900-70y+95y = 13600

11900+25y = 13600

25y = 13600-11900

25y = 1700

y = 1700/25

y = 68

Now, putting this value of y in equation 1:

x = 170-68

x = 102

We are given that

Total length of path=10 mile

Han runs at a pace=12 minutes per mile

Tyler runs at a pace=15 minutes per mile

We have to find the distance run by Han after a half hour.

Half hour=30 minutes

Using unitary method

Han runs distance in 12 minutes=1 mile

Han runs distance in 1 minute= mile

Han runs distance in 30 minutes= miles

Hence, Han runs 2.5 miles after half hour.

Step-by-step explanation:

a) This is a discrete probability distribution because the sum of the probabilities is of 1 and each probability is positive.

b) The distribution is represented by Graph A.

c) The mean is of: 1.559.

d) The standard deviation is of: 1.4

e) The probability that a student is involved in three activities is of 0.151.

f) The probability that a student is involved in three or four activities is of 0.28.

From the table, the distribution is presented as follows:

The sum of these probabilities is of:

0.332 + 0.186 + 0.202 + 0.151 + 0.129 = 1.

Since the sum is of one and none of the probabilities is negative, this is a valid discrete distribution shown by Graph A, as it associates each valeu of the input with it's respective probability.

The mean of the distribution is the sum of each outcome multiplied by it's probability, hence:

E(X) = 0 x 0.332 + 1 x 0.186 + 2 x 0.202 + 3 x 0.151 + 4 x 0.129 = 1.559.

The standard deviation is the square root of the sum of the differences squared between each outcome and the mean, multiplied by it's probability, hence:

S(X) = sqrt((0-1.559)² x 0.332 + (1-1.559)² x 0.186 + (2-1.559)² x 0.202 + (3-1.559)² x 0.151 + (4-1.559)² x 0.129) = 1.4.

Yes, they justified giving us a ticket, even though we were not caught speeding, because we drove at a speed higher than the posted speed limit.

It is given that we are driving down a straight country road. The posted limit is 40 miles per hour along this road. Two police officers are posted one mile apart along this road, tracking vehicle speeds, and are in contact with each other. At the first officer’s position, we drive by going 39 miles per hour. At the second officer’s position, 63 seconds later, we drive by, going 38 miles per hour.

The second officer pulls us over and gives us a ticket. We will use the mean value theorem to check whether getting a ticket was justified or not. Let the maximum speed be "v" that we reach between the officers at time "c". Let the function f(t) denote the distance at time "t".

f'(c) = [f(b) - f(a)]/(b - a)

v = (1 - 0)/(63 - 0)

v = 1/63 miles per second

We need to convert the speed into miles per hour.

v = 3600/63 = 57.143 miles per hour

The speed is higher than the posted speed limit. Hence, they justified giving us a ticket, even though we were not caught speeding.

LIFO                                 $37                  $334

Weighted Average         $41                   $338

The gross profit is the difference between the net sales revenue and the cost of goods sold.

It is the first profit point in the income statement which measures the financial performance of an entity during a period.

The ending inventory is the difference between the cost of goods available for sale and the cost of goods sold, depending on the inventory method in use.

Some of the inventory methods include FIFO, LIFO, Weighted Average, and Specific Identification.

Item       Beta          Units    Cost

April 2   Purchase      1       $165

April 15  Purchase      1        169

April 20 Purchase      1        173

April 27 Sales          1                  $210

Total                           3    $507

Average cost per unit $169 ($507 ÷ 3 units)

Cost of goods available for sale = $507

a) First-in, First-out (FIFO):

Ending inventory = $342 ($169 + $173)

Cost of goods sold = $165 ($507 - $342)

Gross profit = $45 ($210 - $165)

b) Last-in, First-out (LIFO):

Ending inventory = $334 ($165 + $169)

Cost of goods sold = $173 ($507 - $334)

Gross profit = $37 ($210 - $173)

c) Weighted average cost method:

The car which covers 28 miles on 1 gallon of gas that car will take 9 gallons of gas and drives 252 miles.

We know that the relation between distance, speed, and time is given by:

distance = speed * time

speed = distance / time

We are given;

Distance covered by the car = 252 miles

Gas used to cover  252 miles = 9 gallons

We will solve the given problem using the unitary method.

Since for 9 gallons of gas, the car covered a distance of 252 miles.

So, for 1 gallon of gas, the car covered a distance of 252 / 9 miles = 28 miles.
